In verse 14, it was said: ثُمَّ جَعَلْنَاكُمْ خَلَائِفَ فِي الْأَرْ‌ضِ مِن بَعْدِهِمْ لِنَنظُرَ‌ كَيْفَ تَعْمَلُونَ ﴿14﴾ (Then We made you vice-regents on the earth, in order to see how you would act), that is, ` after the destruction of past peoples, We made you successors to them giving you the vice-regency of the earth. But, let this not give you any false idea that this vice-regency of the earth has been given to you so that you could have a good time. In fact, this honor has been bestowed on you to test you and to see how you would act - would you learn your lesson from the history of past peoples or would you lose your head drunk with power and wealth?'

This tells us that worldly power is not something to be proud of or arrogant about. This is responsibility at its toughest, a charge very heavy and very fragile to handle.
